What you wrote seems like a pretty good explanation!

There is no room for 2 entries, the sale and the alternate date for the balance.  Do I have to make two initial entries on Schedule B, one for the shares sold and one for the balance on hand at the alt date.thanks. 

Ah, now I understand what you're trying to do. Yes, two initial entries, one for the shares sold prior to AVD and one for the shares held on AVD. 

I assume you've already determined that the estate is eligible to elect the AVD.
